In anatomy, the canal of the cervix (or endocervical canal, or cervical canal, or cervical canal of uterus, or cavity of cervix) is somewhat fusiform, flattened from before backward, and broader at the middle than at either extremity.
It communicates above through the internal orifice with the cavity of the body, and below through the external orifice with the vaginal cavity.
The wall of the canal presents an anterior and a posterior longitudinal ridge, from each of which proceed a number of small oblique columns, the palmate folds, giving the appearance of branches from the stem of a tree; to this arrangement the name arbor vitæ uterina is applied.
The folds on the two walls are not exactly opposed, but fit between one another so as to close the cervical canal.
